How to unpack an .asar file?

Question

I have packed my electron application using follwoing command

asar pack app app.asar

Now, I need to unpack it and get the whole code back. Is there anyway to do so?

Answer 1

From the asar documentation

(the use of npx here is to avoid to install the asar tool globally with npm install -g asar)

Extract the whole archive:

npx asar extract app.asar destfolder 

Extract a particular file:

npx asar extract-file app.asar main.js

Answer 2

It is possible to upack without node installed using the following 7Zip-plugin:

Thanks @MayaPosch for mentioning that.
